TECHNICAL FIELD

The disclosed embodiments relate generally to portable electronic devices, and more particularly, to portable electronic devices that display structured electronic documents such as web pages on a touch screen display.

BACKGROUND

As portable electronic devices become more compact, and the number of functions performed by a given device increase, it has become a significant challenge to design a user interface that allows users to easily interact with a multifunction device. This challenge is particular significant for handheld portable devices, which have much smaller screens than desktop or laptop computers. This situation is unfortunate because the user interface is the gateway through which users receive not only content but also responses to user actions or behaviors, including user attempts to access a device's features, tools, and functions. Some portable communication devices (e.g., mobile telephones, sometimes called mobile phones, cell phones, cellular telephones, and the like) have resorted to adding more pushbuttons, increasing the density of push buttons, overloading the functions of push buttons, or using complex menu systems to allow a user to access, store and manipulate data. These conventional user interfaces often result in complicated key sequences and menu hierarchies that must be memorized by the user.

Many conventional user interfaces, such as those that include physical pushbuttons, are also inflexible. This may prevent a user interface from being configured and/or adapted by either an application running on the portable device or by users. When coupled with the time consuming requirement to memorize multiple key sequences and menu hierarchies, and the difficulty in activating a desired pushbutton, such inflexibility is frustrating to most users.

In particular, it is slow and tedious to navigate in structured electronic documents (e.g., web pages) in portable electronic devices with small screens using conventional input devices (e.g., 5-way toggle switches). Moreover, it is cumbersome to control and view multimedia content within such documents on portable electronic devices.

Accordingly, there is a need for portable electronic devices with more transparent and intuitive user interfaces for viewing and navigating structured electronic documents and multimedia content within such documents. Such interfaces increase the effectiveness, efficiency and user satisfaction with activities like web browsing on portable electronic devices.

SUMMARY

The above deficiencies and other problems associated with user interfaces for portable devices are reduced or eliminated by the disclosed portable multifunction device. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen”) with a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch-sensitive display. In some embodiments, the functions may include telephoning, video conferencing, e-mailing, instant messaging, blogging, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Instructions for performing these functions may be included in a computer readable storage medium or other computer program product configured for execution by one or more processors.

In one aspect of the invention, a computer-implemented method, for use in conjunction with a portable electronic device with a touch screen display, comprises: displaying at least a portion of a structured electronic document on the touch screen display, wherein the structured electronic document comprises a plurality of boxes of content; detecting a first gesture at a location on the displayed portion of the structured electronic document; determining a first box in the plurality of boxes at the location of the first gesture; and enlarging and substantially centering the first box on the touch screen display.

In another aspect of the invention, a graphical user interface on a portable electronic device with a touch screen display comprises: at least a portion of a structured electronic document, wherein the structured electronic document comprises a plurality of boxes of content. In response to detecting a first gesture at a location on the portion of the structured electronic document, a first box in the plurality of boxes at the location of the first gesture is determined and the first box is enlarged and substantially centered on the touch screen display.

In another aspect of the invention, a portable electronic device comprises: a touch screen display, one or more processors, memory, and one or more programs. The one or more programs are stored in the memory and configured to be executed by the one or more processors. The one or more programs include instructions for displaying at least a portion of a structured electronic document on the touch screen display, wherein the structured electronic document comprises a plurality of boxes of content. The one or more programs also include instructions for detecting a first gesture at a location on the displayed portion of the structured electronic document; instructions for determining a first box in the plurality of boxes at the location of the first gesture; and instructions for enlarging and substantially centering the first box on the touch screen display.

In another aspect of the invention, a computer-program product comprises a computer readable storage medium and a computer program mechanism (e.g., one or more computer programs) embedded therein. The computer program mechanism comprises instructions, which when executed by a portable electronic device with a touch screen display, cause the device to display at least a portion of a structured electronic document on the touch screen display, wherein the structured electronic document comprises a plurality of boxes of content; to detect a first gesture at a location on the displayed portion of the structured electronic document; to determine a first box in the plurality of boxes at the location of the first gesture; and to enlarge and substantially center the first box on the touch screen display.

In another aspect of the invention, a portable electronic device with a touch screen display comprises means for displaying at least a portion of a structured electronic document on the touch screen display, wherein the structured electronic document comprises a plurality of boxes of content; means for detecting a first gesture at a location on the displayed portion of the structured electronic document; means for determining a first box in the plurality of boxes at the location of the first gesture; and means for enlarging and substantially centering the first box on the touch screen display.

The disclosed embodiments allow users to more easily view and navigate structured electronic documents and multimedia content within such documents on portable electronic devices.

DESCRIPTION OF EMBODIMENTS

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first gesture could be termed a second gesture, and, similarly, a second gesture could be termed a first gesture, without departing from the scope of the present invention.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the description of the invention and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Embodiments of a portable multifunction device, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device such as a mobile telephone that also contains other functions, such as PDA and/or music player functions.

The user interface may include a physical click wheel in addition to a touch screen or a virtual click wheel displayed on the touch screen. A click wheel is a user-interface device that may provide navigation commands based on an angular displacement of the wheel or a point of contact with the wheel by a user of the device. A click wheel may also be used to provide a user command corresponding to selection of one or more items, for example, when the user of the device presses down on at least a portion of the wheel or the center of the wheel. Alternatively, breaking contact with a click wheel image on a touch screen surface may indicate a user command corresponding to selection. For simplicity, in the discussion that follows, a portable multifunction device that includes a touch screen is used as an exemplary embodiment. It should be understood, however, that some of the user interfaces and associated processes may be applied to other devices, such as personal computers and laptop computers, which may include one or more other physical user-interface devices, such as a physical click wheel, a physical keyboard, a mouse and/or a joystick.

The device supports a variety of applications, such as one or more of the following: a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a blogging application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that may be executed on the device may use at least one common physical user-interface device, such as the touch screen. One or more functions of the touch screen as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch screen) of the device may support the variety of applications with user interfaces that are intuitive and transparent.

The user interfaces may include one or more soft keyboard embodiments. The soft keyboard embodiments may include standard (QWERTY) and/or non-standard configurations of symbols on the displayed icons of the keyboard, such as those described in U.S. patent application Ser. No. 11/459,606, “Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, and Ser. No. 11/459,615, “Touch Screen Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, the contents of which are hereby incorporated by reference. The keyboard embodiments may include a reduced number of icons (or soft keys) relative to the number of keys in existing physical keyboards, such as that for a typewriter. This may make it easier for users to select one or more icons in the keyboard, and thus, one or more corresponding symbols. The keyboard embodiments may be adaptive. For example, displayed icons may be modified in accordance with user actions, such as selecting one or more icons and/or one or more corresponding symbols. One or more applications on the portable device may utilize common and/or different keyboard embodiments. Thus, the keyboard embodiment used may be tailored to at least some of the applications. In some embodiments, one or more keyboard embodiments may be tailored to a respective user. For example, one or more keyboard embodiments may be tailored to a respective user based on a word usage history (lexicography, slang, individual usage) of the respective user. Some of the keyboard embodiments may be adjusted to reduce a probability of a user error when selecting one or more icons, and thus one or more symbols, when using the soft keyboard embodiments.

Attention is now directed towards embodiments of the device. FIGS. 1A and 1B are block diagrams illustrating portable multifunction devices 100 with touch-sensitive displays 112 in accordance with some embodiments. The touch-sensitive display 112 is sometimes called a “touch screen” for convenience, and may also be known as or called a touch-sensitive display system.

The audio circuitry 110, the speaker 111, and the microphone 113 provide an audio interface between a user and the device 100. The audio circuitry 110 receives audio data from the peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to the speaker 111. The speaker 111 converts the electrical signal to human-audible sound waves. The audio circuitry 110 also receives electrical signals converted by the microphone 113 from sound waves. The audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to the peripherals interface 118 for processing. Audio data may be retrieved from and/or transmitted to memory 102 and/or the RF circuitry 108 by the peripherals interface 118. In some embodiments, the audio circuitry 110 also includes a headset jack (e.g. 212, FIG. 2). The headset jack provides an interface between the audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

The I/O subsystem 106 couples input/output peripherals on the device 100, such as the touch screen 112 and other input/control devices 116, to the peripherals interface 118. The I/O subsystem 106 may include a display controller 156 and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input/control devices 116 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) may include an up/down button for volume control of the speaker 111 and/or the microphone 113. The one or more buttons may include a push button (e.g., 206, FIG. 2). A quick press of the push button may disengage a lock of the touch screen 112 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference. A longer press of the push button (e.g., 206) may turn power to the device 100 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen 112 is used to implement virtual or soft buttons and one or more soft keyboards.

The touch-sensitive touch screen 112 provides an input interface and an output interface between the device and a user. The display controller 156 receives and/or sends electrical signals from/to the touch screen 112. The touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below.

A touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen 112 and the display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on the touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen 112 and the user corresponds to a finger of the user.

The touch screen 112 may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen 112 and the display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen 112.

A touch-sensitive display in some embodiments of the touch screen 112 may be analogous to the multi-touch sensitive tablets described in the Hollowing U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference. However, a touch screen 112 displays visual output from the portable device 100, whereas touch sensitive tablets do not provide visual output.

A touch-sensitive display in some embodiments of the touch screen 112 may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser. No. 11/038,590, “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed Jan. 18, 2005; (6) U.S. patent application Ser. No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein.

The touch screen 112 may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch screen has a resolution of approximately 160 dpi. The user may make contact with the touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, the device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

In some embodiments, the device 100 may include a physical or virtual click wheel as an input control device 116. A user may navigate among and interact with one or more graphical objects (henceforth referred to as icons) displayed in the touch screen 112 by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller 160 as well as one or more of the modules and/or sets of instructions in memory 102. For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen 112 and the display controller 156, respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen.

The device 100 also includes a power system 162 for powering the various components. The power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

The device 100 may also include one or more optical sensors 164. FIGS. 1A and 1B show an optical sensor coupled to an optical sensor controller 158 in I/O subsystem 106. The optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module 143 (also called a camera module), the optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of the device 100, opposite the touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for either still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor 164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor 164 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

The device 100 may also include one or more proximity sensors 166. FIGS. 1A and 1B show a proximity sensor 166 coupled to the peripherals interface 118. Alternately, the proximity sensor 166 may be coupled to an input controller 160 in the I/O subsystem 106. The proximity sensor 166 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 11/240,788, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005; Ser. No. 11/620,702, filed Jan. 7, 2007, “Using Ambient Light Sensor To Augment Proximity Sensor Output;” Ser.

In some embodiments, the device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen 112 and/or a touchpad. By using a touch screen and/or a touchpad as the primary input/control device for operation of the device 100, the number of physical input/control devices (such as push buttons, dials, and the like) on the device 100 may be reduced.

The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates the device 100 to a main, home, or root menu from any user interface that may be displayed on the device 100. In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input/control device instead of a touchpad.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen may display one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user may select one or more of the graphics by making contact or touching the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the contact may include a gesture, such as one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with the device 100. In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap.

The device 100 may also include one or more physical buttons, such as “home” or menu button 204. As described previously, the menu button 204 may be used to navigate to any application 136 in a set of applications that may be executed on the device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI in touch screen 112.

In some embodiments, the device detects contact with the touch-sensitive display (e.g., a user's finger making contact on or near the unlock image 302) while the device is in a user-interface lock state. The device moves the unlock image 302 in accordance with the contact. The device transitions to a user-interface unlock state if the detected contact corresponds to a predefined gesture, such as moving the unlock image across channel 306. Conversely, the device maintains the user-interface lock state if the detected contact does not correspond to the predefined gesture. As noted above, processes that use gestures on the touch screen to unlock the device are described in U.S. patent application Ser. No. 11/322,549, “Unlocking A Device By Performing Gestures On An Unlock Image,” filed Dec. 23, 2005, and Ser.

Similarly, in response to a single tap gesture 3925 on block 3914-2, block 3914-2 may be enlarged with a zooming animation and two-dimensionally scrolled to the center of the display (not shown).

In some embodiments, the device analyzes the render tree of the web page 3912 to determine the blocks 3914 in the web page. In some embodiments, a block 3914 corresponds to a render node that is: a replaced inline; a block; an inline block; or an inline table.

In some embodiments, in response to the same predefined gesture by the user on a block 3914 (e.g., a single tap gesture or a double tap gesture) that is already enlarged and centered, the enlargement and/or centering is substantially or completely reversed. For example, in response to a single tap gesture 3929 (FIG. 5C) on block 3914-5, the web page image may zoom out and return to UI 3900A, FIG. 5A.

In some embodiments, in response to a predefined gesture (e.g., a single tap gesture or a double tap gesture) by the user on a block 3914 that is already enlarged but not centered, the block is centered (or substantially centered) in the web page display. For example, in response to a single tap gesture 3927 (FIG. 5C) on block 3914-4, block 3914-4 may be centered (or substantially centered) in the web page display. Similarly, in response to a single tap gesture 3935 (FIG. 5C) on block 3914-6, block 3914-6 may be centered (or substantially centered) in the web page display. Thus, for a web page display that is already enlarged, in response to a predefined gesture, the device may display in an intuitive manner a series of blocks that the user wants to view. This same gesture may initiate different actions in different contexts (e.g., (1) zooming and/or enlarging in combination with scrolling when the web page is reduced in size, UI 3900A and (2) reversing the enlargement and/or centering if the block is already centered and enlarged).

In some embodiments, in response to a multi-touch 3931 and 3933 de-pinching gesture by the user (FIG. 5C), the web page may be enlarged. Conversely, in response to a multi-touch pinching gesture by the user, the web page may be reduced.

In some embodiments, in response to a substantially vertical upward (or downward) swipe gesture by the user, the web page (or, more generally, other electronic documents) may scroll one-dimensionally upward (or downward) in the vertical direction. For example, in response to an upward swipe gesture 3937 by the user that is within a predetermined angle (e.g., 27) of being perfectly vertical, the web page may scroll one-dimensionally upward in the vertical direction.

Conversely, in some embodiments, in response to a swipe gesture that is not within a predetermined angle (e.g., 27°) of being perfectly vertical, the web page may scroll two-dimensionally (i.e., with simultaneous movement in both the vertical and horizontal directions). For example, in response to an upward swipe gesture 3939 (FIG. 5C) by the user that is not within a predetermined angle (e.g., 27°) of being perfectly vertical, the web page may scroll two-dimensionally along the direction of the swipe 3939.

In some embodiments, in response to a multi-touch 3941 and 3943 rotation gesture by the user (FIG. 5C), the web page may be rotated exactly 90° (UI 3900D, FIG. 5D) for landscape viewing, even if the amount of rotation in the multi-touch 3941 and 3943 rotation gesture is substantially different from 90°. Similarly, in response to a multi-touch 3945 and 3947 rotation gesture by the user (UI 3900D, FIG. 5D), the web page may be rotated exactly 90° for portrait viewing, even if the amount of rotation in the multi-touch 3945 and 3947 rotation gesture is substantially different from 90°.

Thus, in response to imprecise gestures by the user, precise movements of graphics occur. The device behaves in the manner desired by the user despite inaccurate input by the user. Also, note that the gestures described for UI 3900C, which has a portrait view, are also applicable to UIs with a landscape view (e.g., UI 3900D, FIG. 5D) so that the user can choose whichever view the user prefers for web browsing.

FIGS. 6A-6C are flow diagrams illustrating a process 6000 for displaying structured electronic documents such as web pages on a portable electronic device with a touch screen display (e.g., device 100) in accordance with some embodiments. The portable electronic device displays at least a portion of a structured electronic document on the touch screen display. The structured electronic document comprises a plurality of boxes of content (e.g., blocks 3914, FIG. 5A) (6006).

In some embodiments, the plurality of boxes is defined by a style sheet language. In some embodiments, the style sheet language is a cascading style sheet language. In some embodiments, the structured electronic document is a web page (e.g., web page 3912, FIG. 5A). In some embodiments, the structured electronic document is an HTML or XML document.

In some embodiments, displaying at least a portion of the structured electronic document comprises scaling the document width to fit within the touch screen display width independent of the document length (6008).

In some embodiments, the touch screen display is rectangular with a short axis and a long axis (also called the minor axis and major axis); the display width corresponds to the short axis (or minor axis) when the structured electronic document is seen in portrait view (e.g., FIG. 5C); and the display width corresponds to the long axis (or major axis) when the structured electronic document is seen in landscape view (e.g., FIG. 5D).

In some embodiments, prior to displaying at least a portion of a structured electronic document, borders, margins, and/or paddings arc determined for the plurality of boxes (6002) and adjusted for display on the touch screen display (6004). In some embodiments, all boxes in the plurality of boxes are adjusted. In some embodiments, just the first box is adjusted. In some embodiments, just the first box and boxes adjacent to the first box are adjusted.

A first gesture is detected at a location on the displayed portion of the structured electronic document (e.g., gesture 3923, FIG. 5A) (6010). In some embodiments, the first gesture is a finger gesture. In some embodiments, the first gesture is a stylus gesture.

In some embodiments, the first gesture is a tap gesture. In some embodiments, the first gesture is a double tap with a single finger, a double tap with two fingers, a single tap with a single finger, or a single tap with two fingers.

A first box (e.g., Block 5 3914-5, FIG. 5A) in the plurality of boxes is determined at the location of the first gesture (6012). In some embodiments, the structured electronic document has an associated render tree with a plurality of nodes and determining the first box at the location of the first gesture comprises: traversing down the render tree to determine a first node in the plurality of nodes that corresponds to the detected location of the first gesture (6014); traversing up the render tree from the first node to a closest parent node that contains a logical grouping of content (6016); and identifying content corresponding to the closest parent node as the first box (6018). In some embodiments, the logical grouping of content comprises a paragraph, an image, a plugin object, or a table. In some embodiments, the closest parent node is a replaced inline, a block, an inline block, or an inline table.

The first box is enlarged and substantially centered on the touch screen display (e.g., Block 5 3914-5, FIG. 5C) (6020). In some embodiments, enlarging and substantially centering comprises simultaneously zooming and translating the first box on the touch screen display (6022). In some embodiments, enlarging comprises expanding the first box so that the width of the first box is substantially the same as the width of the touch screen display (6024).

In some embodiments, text in the enlarged first box is resized to meet or exceed a predetermined minimum text size on the touch screen display (6026). In some embodiments, the text resizing comprises: determining a scale factor by which the first box will be enlarged (6028); dividing the predetermined minimum text size on the touch screen display by the scaling factor to determine a minimum text size for text in the first box (6030); and if a text size for text in the first box is less than the determined minimum text size, increasing the text size for text in the first box to at least the determined minimum text size (6032). In some embodiments, the first box has a width; the display has a display width; and the scale factor is the display width divided by the width of the first box prior to enlarging. In some embodiments, the resizing occurs during the enlarging. In some embodiments, the resizing occurs after the enlarging.

For example, suppose the predetermined minimum text size is an 18-point font and the scale factor is determined to be two. In that case, the minimum text size for text in the first box is 18 divided by 2, or 9. If text in the first box is in a 10-point font, its text size is not increased, because 10 is greater than the 9-point minimum. Once the scale factor is applied, the text will be displayed in a 20-point font, which is greater than the predetermined minimum text size of 18. If, however, text in the first box is in an 8-point font, application of the scale factor would cause the text to be displayed in a 16-point font, which is less than the predetermined minimum text size of 18. Therefore, since 8 is less than 9, the text size is increased to at least a 9-point font and displayed in at least an 18-point font after application of the scale factor.

In some embodiments, text in the structured electronic document is resized to meet or exceed a predetermined minimum text size on the touch screen display (6026; FIG. 6B). In some embodiments, the text resizing comprises: determining a scale factor by which the first box will be enlarged (6028); dividing the predetermined minimum text size on the touch screen display by the scaling factor to determine a minimum text size for text in the structured electronic document (6030); and if a text size for text in the structured electronic document is less than the determined minimum text size, increasing the text size for text in the structured electronic document to at least the determined minimum text size (6032). In some embodiments, the text resizing comprises: identifying boxes containing text in the plurality of boxes; determining a scale factor by which the first box will be enlarged; dividing the predetermined minimum text size on the touch screen display by the scaling factor to determine a minimum text size for text in the structured electronic document; and for each identified box containing text, if a text size for text in the identified box is less than the determined minimum text size, increasing the text size for text in the identified box to at least the determined minimum text size and adjusting the size of the identified box to accommodate the resized text.

In some embodiments, a second gesture (e.g., gesture 3929, FIG. 5C) is detected on the enlarged first box (6034). In response to detecting the second gesture, the displayed portion of the structured electronic document is reduced in size (6036). In some embodiments, the first box returns to its size prior to being enlarged (6038).

In some embodiments, the second gesture and the first gesture are the same type of gesture. In some embodiments, the second gesture is a finger gesture. In some embodiments, the second gesture is a stylus gesture.

In some embodiments, the second gesture is a tap gesture. In some embodiments, the second gesture is a double tap with a single finger, a double tap with two fingers, a single tap with a single finger, or a single tap with two fingers.

In some embodiments, while the first box is enlarged, a third gesture (e.g., gesture 3927 or gesture 3935, FIG. 5C) is detected on a second box other than the first box (6040). In response to detecting the third gesture, the second box is substantially centered on the touch screen display (6042). In some embodiments, the third gesture and the first gesture are the same type of gesture. In some embodiments, the third gesture is a finger gesture. In some embodiments, the third gesture is a stylus gesture.

In some embodiments, the third gesture is a tap gesture. In some embodiments, the third gesture is a double tap with a single finger, a double tap with two fingers, a single tap with a single finger, or a single tap with two fingers.

In some embodiments, a swipe gesture (e.g., gesture 3937 or gesture 3939, FIG. 5C) is detected on the touch screen display (6044; FIG. 6C). In response to detecting the swipe gesture, the displayed portion of the structured electronic document is translated on the touch screen display (6046). In some embodiments, the translating comprises vertical, horizontal, or diagonal movement of the structured electronic document on the touch screen display (6048). In some embodiments, the swipe gesture is a finger gesture. In some embodiments, the swipe gesture is a stylus gesture.

In some embodiments, a fifth gesture (e.g., multi-touch gesture 3941/3943, FIG. 5C) is detected on the touch screen display (6050). In response to detecting the fifth gesture, the displayed portion of the structured electronic document is rotated on the touch screen display by 90° (6052). In some embodiments, the fifth gesture is a finger gesture. In some embodiments, the fifth gesture is a multifinger gesture. In some embodiments, the fifth gesture is a twisting gesture.

In some embodiments, a change in orientation of the device is detected (6054). For example, the one or more accelerometers 168 (FIGS. 1A-1B) detect a change in orientation of the device. In response to detecting the change in orientation of the device, the displayed portion of the structured electronic document is rotated on the touch screen display by 90° (6056).

In some embodiments, a multi-finger de-pinch gesture (e.g., multi-touch gesture 3931/3933, FIG. 5C) is detected on the touch screen display (6058). In response to detecting the multi-finger de-pinch gesture, a portion of the displayed portion of the structured electronic document is enlarged on the touch screen display in accordance with a position of the multi-finger de-pinch gesture and an amount of finger movement in the multi-finger de-pinch gesture (6060).

While the content display process 6000 described above includes a number of operations that appear to occur in a specific order, it should be apparent that the process 6000 can include more or fewer operations, which can be executed serially or in parallel (e.g., using parallel processors or a multi-threading environment), an order of two or more operations may be changed and/or two or more operations may be combined into a single operation.

A graphical user interface (e.g., UI 3900A, FIG. 5A) on a portable electronic device with a touch screen display comprises at least a portion of a structured electronic document (e.g., web page 3912, FIG. 5A). The structured electronic document comprises a plurality of boxes of content (e.g., blocks 3914, FIG. 5A). In response to detecting a first gesture (e.g., gesture 3923, FIG. 5A) at a location on the portion of the structured electronic document, a first box (e.g., Block 5 3914-5, FIG. 5A) in the plurality of boxes at the location of the first gesture is determined and the first box is enlarged and substantially centered on the touch screen display (e.g., Block 5 3914-5, FIG. 5C).

In some embodiments, in response to a tap or other predefined user gesture on URL entry box 3908, the touch screen displays an enlarged entry box 3926 and a keyboard 616 (e.g., UI 3900B, FIG. 5B in portrait viewing and UI 3900E, FIG. 5E in landscape viewing). In some embodiments, the touch screen also displays:

-   -   Contextual clear icon 3928 that when activated (e.g., by a         finger tap on the icon) initiates deletion of all text in entry         box 3926;     -   a search icon 3930 that when activated (e.g., by a finger tap on         the icon) initiates an Internet search using the search terms         input in box 3926; and     -   Go to URL icon 3932 that when activated (e.g., by a finger tap         on the icon) initiates acquisition of the web page with the URL         input in box 3926;

Thus, the same entry box 3926 may be used for inputting both search terms and URLs. In some embodiments, whether or not clear icon 3928 is displayed depends on the context.

UI 3900G (FIG. 5G) is a UI for adding new windows to an application, such as the browser 147. UI 3900G displays an application (e.g., the browser 147), which includes a displayed window (e.g., web page 3912-2) and at least one hidden window (e.g., web pages 3912-1 and 3934-3 and possibly other web pages that are completely hidden off-screen). UI 3900G also displays an icon for adding windows to the application (e.g., new window or new page icon 3936). In response to detecting activation of the icon 3936 for adding windows, the browser adds a window to the application (e.g., a new window for a new web page 3912).

In response to detecting a gesture on the touch screen display, a displayed window in the application is moved off the display and a hidden window is moved onto the display. For example, in response to detecting a tap gesture 3949 on the left side of the screen, the window with web page 3912-2 is moved partially or fully off-screen to the right, the window with web page 3912-3 is moved completely off-screen, partially hidden window with web page 3912-1 is moved to the center of the display, and another completely hidden window with a web page (e.g., 3912-0) may be moved partially onto the display. Alternatively, detection of a left-to-right swipe gesture 3951 may achieve the same effect.

Conversely, in response to detecting a tap gesture 3953 on the right side of the screen, the window with web page 3912-2 is moved partially or fully off-screen to the left, the window with web page 3912-1 is moved completely off-screen, partially hidden window with web page 3912-3 is moved to the center of the display, and another completely hidden window with a web page (e.g., 3912-4) may be moved partially onto the display. Alternatively, detection of a right-to-left swipe gesture 3951 may achieve the same effect.

In some embodiments, in response to a tap or other predefined gesture on a delete icon 3934, the corresponding window 3912 is deleted. In some embodiments, in response to a tap or other predefined gesture on Done icon 3938, the window in the center of the display (e.g., 3912-2) is enlarged to fill the screen.

Additional description of adding windows to an application can be found in U.S. patent application Ser. No. 11/620,647, “Method, System, And Graphical User Interface For Viewing Multiple Application Windows,” filed Jan. 5, 2007, the content of which is hereby incorporated by reference.

FIGS. 7A-7F illustrate exemplary user interfaces for playing an item of inline multimedia content in accordance with some embodiments.

In some embodiments, user interfaces 4000A-4000F (in FIGS. 7A-7F, respectively) include the following elements, or a subset or superset thereof:

-   -   402, 404, 406, 3902, 3906, 3910, 3912, 3918, 3920, 3922, as         described above;     -   inline multimedia content 4002, such as QuickTime content         (4002-1), Windows Media content (4002-2), or Flash content         (4002-3);     -   other types of content 4004 in the structured document, such as         text;     -   Exit icon 4006 that when activated (e.g., by a finger tap on the         icon) initiates exiting the inline multimedia content player UI         (e.g., UI 4000B or 4000F) and returning to another UI (e.g., UI         4000A, FIG. 7A):     -   Lapsed time 4008 that shows how much of the inline multimedia         content 4002 has been played, in units of time;     -   Progress bar 4010 that indicates what fraction of the inline         multimedia content 4002 has been played and that may be used to         help scroll through the inline multimedia content in response to         a user gesture;     -   Remaining time 4012 that shows how much of the inline multimedia         content 4002 remains to be played, in units of time;     -   Downloading icon 4014 that indicates when inline multimedia         content 4002 is being downloaded or streamed to the device;     -   Fast Reverse/Skip Backwards icon 4016 that when activated (e.g.,         by a finger tap on the icon) initiates reversing or skipping         backwards through the inline multimedia content 4002;     -   Play icon 4018 that when activated (e.g., by a finger tap 4026         (FIG. 7C) on the icon) initiates playing the inline multimedia         content 4002, either from the beginning or from where the inline         multimedia content was paused;     -   Fast Forward/Skip Forward icon 4020 that initiates forwarding or         skipping forwards through the inline multimedia content 4002;     -   Volume adjustment slider icon 4022 that that when activated         (e.g., by a finger tap on the icon) initiates adjustment of the         volume of the inline multimedia content 4002; and     -   Pause icon 4024 that when activated (e.g., by a finger tap on         the icon) initiates pausing the inline multimedia content 4002.

FIG. 8 is a flow diagram illustrating a process 8000 for displaying inline multimedia content on a portable electronic device with a touch screen display (e.g., device 100) in accordance with some embodiments. The portable electronic device displays at least a portion of a structured electronic document on the touch screen display (8002). The structured electronic document comprises content (e.g., content 4002 and 4004, FIG. 7A). In some embodiments, the structured electronic document is a web page (e.g., web page 3912). In some embodiments, the structured electronic document is an HTML or XML document.

A first gesture (e.g., gesture 4028, FIG. 7A) is detected on an item of inline multimedia content (e.g., content 4002-1, FIG. 7A) in the displayed portion of the structured electronic document (8004). In some embodiments, the inline multimedia content comprises video and/or audio content. In some embodiments, the content can be played with a QuickTime, Windows Media, or Flash plugin.

In response to detecting the first gesture, the item of inline multimedia content is enlarged on the touch screen display and other content (e.g., content 4004 and other content 4002 besides 4002-1, FIG. 7A) in the structured electronic document besides the enlarged item of inline multimedia content ceases to be displayed (e.g., UI 4000B, FIG. 7B or UI 4000F, FIG. 7F) (8006).

In some embodiments, enlarging the item of inline multimedia content comprises animated zooming in on the item. In some embodiments, enlarging the item of inline multimedia content comprises simultaneously zooming and translating the item of inline multimedia content on the touch screen display. In some embodiments, enlarging the item of inline multimedia content comprises rotating the item of inline multimedia content by 90° (e.g., from UI 4000A, FIG. 7A to UI 4000B, FIG. 7B).

In some embodiments, the item of inline multimedia content has a full size; the touch screen display has a size; and enlarging the item of inline multimedia content comprises enlarging the item of inline multimedia content to the smaller of the full size of the item and the size of the touch screen display.

In some embodiments, enlarging the item of inline multimedia content comprises expanding the item of inline multimedia content so that the width of the item of inline multimedia content is substantially the same as the width of the touch screen display (e.g., UI 4000B, FIG. 7B or UI 4000F, FIG. 7F).

In some embodiments, ceasing to display other content in the structured electronic document besides the item of inline multimedia content comprises fading out the other content in the structured electronic document besides the item of inline multimedia content.

While the enlarged item of inline multimedia content is displayed, a second gesture is detected on the touch screen display (e.g., gesture 4030, FIG. 7B) (8008).

In response to detecting the second gesture, one or more playback controls for playing the enlarged item of inline multimedia content are displayed (8010). In some embodiments, the one or more playback controls comprise a play icon (e.g., icon 4018, FIG. 7C), a pause icon (e.g., icon 4024, FIG. 7E), a sound volume icon (e.g., icon 4022), and/or a playback progress bar icon (e.g., icon 4010).

In some embodiments, displaying one or more playback controls comprises displaying one or more playback controls on top of the enlarged item of inline multimedia content (e.g., playback controls 4016, 4018, 4020, and 4022 are on top of enlarged inline multimedia content 4002-1 in FIG. 7C). In some embodiments, the one or more playback controls are superimposed on top of the enlarged item of inline multimedia content. In some embodiments, the one or more playback controls are semitransparent.

In some embodiments, an instruction in the structured electronic document to automatically start playing the item of inline multimedia content is overridden, which gives the device time to download more of the selected inline multimedia content prior to starting playback.

A third gesture is detected on one of the playback controls (e.g., gesture 4026 on play icon 4018, FIG. 7C) (8012).

In response to detecting the third gesture, the enlarged item of inline multimedia content is played (8014). In some embodiments, playing the enlarged item of inline multimedia content comprises playing the enlarged item of inline multimedia content with a plugin for a content type associated with the item of inline multimedia content.

In some embodiments, while the enlarged item of inline multimedia content is played, the one or more playback controls cease to be displayed (e.g., FIG. 7D, which no longer displays playback controls 4016, 4018, 4020, and 4022, but still shows 4006, 4008, 4010, and 4012). In some embodiments, all of the playback controls cease to be displayed. In some embodiments, ceasing to display the one or more playback controls comprises fading out the one or more playback controls. In some embodiments, the display of the one or more playback controls is ceased after a predetermined time. In some embodiments, the display of the one or more playback controls is ceased after no contact is detected with the touch screen display for a predetermined time.

In some embodiments, a fourth gesture is detected on the touch screen display (8016). In response to detecting the fourth gesture, at least the portion of the structured electronic document is displayed again (e.g., FIG. 7A) (8018). In some embodiments, the fourth gesture comprises a tap gesture on a playback completion icon, such as a done icon (e.g., gesture 4032 on done icon 4006, FIG. 7D). In some embodiments, the item of inline multimedia content returns to its size prior to being enlarged.

In some embodiments, the first, second, and third gestures are finger gestures. In some embodiments, the first, second, and third gestures are stylus gestures.

In some embodiments, the first, second, and third gestures are tap gestures. In some embodiments, the tap gesture is a double tap with a single finger, a double tap with two fingers, a single tap with a single finger, or a single tap with two fingers.

While the multimedia display process 8000 described above includes a number of operations that appear to occur in a specific order, it should be apparent that the process 8000 can include more or fewer operations, which can be executed serially or in parallel (e.g., using parallel processors or a multi-threading environment), an order of two or more operations may be changed and/or two or more operations may be combined into a single operation.

A graphical user interface on a portable electronic device with a touch screen display comprises: at least a portion of a structured electronic document, wherein the structured electronic document comprises content; an item of inline multimedia content in the portion of the structured electronic document; and one or more playback controls. In response to detecting a first gesture on the item of inline multimedia content, the item of inline multimedia content on the touch screen display is enlarged, and display of other content in the structured electronic document besides the enlarged item of inline multimedia content is ceased. In response to detecting a second gesture on the touch screen display while the enlarged item of inline multimedia content is displayed, the one or more playback controls for playing the enlarged item of in line multimedia content are displayed. In response to detecting a third gesture on one of the playback controls, the enlarged item of inline multimedia content is played.
